What does a black speed limit sign mean?

The "Night Speed Limit" sign indicates that a reduced speed limit is in effect during nighttime hours. This sign is used to ensure safer driving conditions after dark when visibility is lower and road hazards may be more difficult to see. Drivers are required to adhere to the lower speed limit during the specified nighttime period, which typically starts at dusk and continues until dawn.
